About Chemical Weathering
"A process called ""weathering"" is responsible for most of the changes made to the geology of the earth’s surface. It can be affected by different factors, and is grouped into two major categories: mechanical and chemical. Chemical weathering causes"... More »

Chemical weathering is much more common in locations where there is a lot of water. This is because water is important to many of the chemical reactions that can take place. Warmer temperatures are also more friendly to chemical weathering. The most common types of chemical weathering are oxidation, hydrolysis and ...


Chemical weathering is the breakdown of rocks into sediment by chemical processes. The reader who does not appreciate chemistry may skip the chemical formulas in this article and simply note the results of the reactions, as described in the summary section below. The results themselves cannot be skipped over: ...


This is the decomposition of rocks due to chemical reactions occurring between the minerals in rocks and the environment. The examples below illustrate chemical weathering. Water Water, and many chemical compounds found in water, is the main agent of chemical weathering. Feldspar, one of the most abundant ...


Find animations dealing with chemical weathering. There are also links for accessing images relating to chemical weathering.


Chemical weathering wears down rocks through chemical reactions.


...granodiorites), is common in many pegmatite masses, and constitutes one of the chief components of many metamorphic rocks (e.g., gneisses, schists, and hornfelses). It alters rather easily during chemical weathering and thus is rare in sediments and sedimentary rocks. One stage in the weathering of biotite has resulted ...


Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic. Where does it occur? These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp ...


Chemical weathering definition, any of the various weathering processes that cause exposed rock to undergo chemical decomposition, changing the chemical and mineralogical composition of the rock: Oxygen and acids are agents in chemical weathering. See more.


Chemical weathering results from chemical changes to minerals that become unstable when they are exposed to surface conditions. The kinds of changes that take place are highly specific to the mineral and the environmental conditions. Some minerals, like quartz, are virtually unaffected by chemical weathering, while  ...
